An 'ABers health warning' - Crimeshare (in my opinion) is a useful way at getting at some of the truth behind a particular situation, but you cannot always believe all you read.

If you are getting what you want from II in terms of exchanges, then I would question whay you want to change. Points (in my opinion) is a complete farce and it was invented by the timeshare industry so it could keep selling the poor punters something once the sales of new timeshare became saturated. The way it is claimed to work is that you buy Points (plus the obligatory extra annual maintenance fees on the Points) to add to your 'poor quality' and your trading power is enhanced. Think about it - the amount of good quality timeshare out there is fixed, so buying more points makes you worth more? No - because everyone is clammering to aspire to the same small number of Gold Crown Resorts (best quality). For people who own at a Gold Crown resort, it just means more people are trying to get into the same number of resorts.
